已知输入信号抽样值为+1065个量化单位,采用13折线A律编码,编码器输出的码组和量化误差分别是( )。
A: 1 1 1 1 0 0 0 0 ,15个量化单位
B: 1 1 1 1 0 0 1 1 ,9个量化单位
C: 0 1 1 1 0 0 0 0, 9个量化单位
D: 1 1 1 1 0 0 0 0 ,9个量化单位
A: 1 1 1 1 0 0 0 0 ,15个量化单位
B: 1 1 1 1 0 0 1 1 ,9个量化单位
C: 0 1 1 1 0 0 0 0, 9个量化单位
D: 1 1 1 1 0 0 0 0 ,9个量化单位
举一反三
- 样值为-99个量化单位,采用13折线A律编码,其极性码为 ;段落码为 。 A: 1, 001; B: 0, 011; C: 0, 010; D: 1, 011
- 样值为-99个量化单位,采用13折线A律编码,其极性码为;段落码为。 A: 1, 001 B: 0, 011 C: 0, 010 D: 1, 011
- 将二进制序列编为HDB3码,其中输出正电平用“+1”表示,负电平用“-1”表示,信息代码100000000011编码后表示为( ) A: +1 -1 0 0 +1 -1 0 0 -1 0 +1<br/>-1 B: +1 0 0 0 +1 -1 0 0 -1 0 +1 -1 C: -1 0 0 0 +1 -1 0 0 -1 0 +1 -1 D: +1 0 0 0 +1 -1 0 0 +1 0 -1 +1
- 对信码1000100100001000011000011进行HDB3编码,结果可能是( )。 A: -1 0 0 0 +1 0 0 -1 0 0 0 -V +1 0 0 0 +V -1 +1 -B 0 0 -V +1 -1 B: +1 0 0 0 -1 0 0 +1 0 0 0 +V -1 0 0 0 -V +1 -1 +B 0 0 +V -1 +1 C: +1 0 0 0 -1 0 0 +1 0 0 0 +1 -1 0 0 0 -1 +1 -1 +1 0 0 +1 -1 +1 D: -1 0 0 0 +1 0 0 -1 0 0 0 +V +1 0 0 0 +V -1 +1 +B 0 0 -V +1 -1
- 以下HDB3码中,哪些可以确定其中有误码 A: +1 0 0 0 -1 0 +1 -1 +1 0 0 +1 0 -1 +1 -1 0 0 -1 +1…… B: +1 0 0 -1 +1 0 0 0 +1 -1 0 0 -1 0 0 0 +1 0 0 +1 -1…… C: -1 0 0 0 -1 0 +1 0 0 0 +1 -1 +1 0 0 +1 0 0 -1 +1…… D: -1 0 +1 0 0 0 -1 +1 0 0 0 +1 -1 +1 -1 0 0 -1 +1 0 -1……
